Buying Beam Dumps
Various kinds of beam dumps can be used for temporarily or permanently blocking a laser beam, often for reasons of laser safety. High-power versions are fan-cooled or water-cooled to safely dissipate the absorbed laser energy, ensuring safe operation in laboratory and industrial environments.

Like our high power HP Series, these beam dumps have a highly resistant absorber that can withstand 4 kW or even 12 kW in continuous mode. Their very large aperture of 100 mm in diameter accommodates even the largest beams. |
 The Future Depends on Optics Edmund Optics101 East Gloucester Pike Barrington, NJ 08007 United States See us at SPIE Photonics West 2025 in San Francisco, January 25–30 (booth 1139)! |  Edmund Optics offers Acktar blackened laser beam traps and blocks and other kinds of beam dumps. |
 We like it black ACM Coatings GmbH (subsidiary of Acktar Ltd.)Jakobsring 3 06618 Naumburg (Saale) Germany See us at SPIE Photonics West 2025 in San Francisco, January 25–30 (booth 4639)! |  Acktar's laser beam dumps increase safety and reduce the risk of laser damage by trapping the beam entered into the aperture. They fit for most beam sizes and can be used in a lab or any other optical system. They are suitable for CW and pulsed beams up to 20 W/cm2 (tested value). They are available for a wide wavelength range from EUV through VIS and up to the LWIR. The built-in mounting suits a standard optical stand (M6 × 1.0) and can be easily held. In addition to the unique design the advantage of having Acktar’s coatings implemented into the device you get the reflectivity factor of less than 10−6. |
